Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing technology, specifically to a leak-proof detection device for welding automotive ECU bracket nuts. Background Technology
[0002] The installation location of an automotive ECU (Electric Control Unit) is greatly influenced by the overall layout space within the engine compartment. The engine compartment contains numerous structures, leaving very limited space for the ECU. The design of the ECU mounting bracket must not only meet the requirements of the surrounding environment but also satisfy strength, rigidity, and modal performance requirements. To facilitate ECU bracket installation, the bracket has several mounting holes. Depending on installation needs, some holes are welded with nuts, while others are not. During the ECU bracket manufacturing process, it is common to find holes without nuts, or nuts welded to holes where they are not needed. Since there are many nuts welded onto the ECU bracket, relying solely on visual inspection for miswelding or missing welds can easily lead to errors. Therefore, this invention provides an automotive ECU bracket nut welding leak detection device, which can detect missing or miswelded nuts on the ECU bracket. Utility Model Content
[0003] In order to overcome the above-mentioned defects in the prior art, this utility model provides a detection device for preventing leakage during welding of automotive ECU bracket nuts.
[0004] A device for detecting leaks in the welding of automotive ECU bracket nuts includes a mounting plate with a sensor corresponding to a welded nut on the ECU bracket. A conveyor belt with a support block is mounted on the conveyor belt. The ECU bracket is placed on the support block, which has a positioning block corresponding to a weight-reducing hole on the ECU bracket. The positioning block is embedded in the weight-reducing hole. When the conveyor belt transports the ECU bracket to the detection point, the mounting plate rises, and the sensor on the mounting plate contacts the corresponding nut on the ECU bracket for detection. The mounting plate also has a top pin with a diameter adapted to the diameter of the mounting hole of the unwelded nut.
[0005] Furthermore, the mounting plate is connected to the output end of the lifting cylinder, the lifting cylinder is mounted on the conveyor frame, and the mounting plate is slidably connected to the conveyor frame via a guide rod.
[0006] Furthermore, the conveyor frame is equipped with a gantry frame at the material feeding point. The slide on the gantry frame moves horizontally by a motor-driven lead screw mechanism. The slide is equipped with a telescopic cylinder, and the output end of the telescopic cylinder is equipped with a vacuum suction cup.
[0007] Furthermore, one side of the conveyor is provided with a collection box for collecting ECU brackets for collecting incompletely welded and mis-welded nuts.
[0008] Furthermore, a collection box is provided below the conveyor belt at the end of the conveyor belt. The collection box is used to collect qualified products. A rotating cam is provided above the collection box. Two rotating cams are located at both ends above the ECU bracket and are connected by a connecting rod. The connecting rod is connected to the output end of the drive motor. When the ECU bracket is conveyed to the lower layer of the conveyor belt, the rotating cam rotates and its distal end contacts the ECU bracket, which can push the ECU bracket away from the positioning block.
[0009] Due to the adoption of the above technical solution, the beneficial technical effects of this utility model are as follows: In this utility model, the ECU bracket is placed on the conveyor belt and positioned by the positioning block. When the ECU bracket is transported to the detection point, the mounting plate rises, and the sensor on the mounting plate detects the welded nut. If the sensor detects a nut that is not welded, the sensor sends a signal, and the top pin also rises. The installation position of the top pin corresponds to the position of the mounting hole of the unwelded nut. If a nut is incorrectly welded to a mounting hole, the rising top pin will lift the ECU bracket, thus preventing the sensor from detecting the nut. The sensor sends a signal, thereby detecting the ECU bracket with incorrectly welded or missing nuts and separating the ECU bracket with incorrectly welded or missing nuts from the qualified ECU bracket, thus improving the detection efficiency and detection accuracy.

[0018] To more clearly illustrate the technical solution of this utility model, the following description is made in conjunction with the accompanying drawings. Obviously, the drawings described below are only one embodiment of this utility model. For those skilled in the art, other embodiments can be obtained based on these drawings and embodiments without creative effort, and all of them fall within the protection scope of this utility model.
[0019] according to Figure 1-7 As shown, an automotive ECU bracket nut welding leak detection device includes a mounting plate 1, on which a sensor 2 is provided. The sensor 2 corresponds to the welding nut 3 on the ECU bracket 21. A conveyor belt 5 is provided on the conveyor belt 5, and a support block 6 is provided on the conveyor belt 5. The ECU bracket 21 is placed on the support block 6. The support block 6 is provided with a positioning block 7 corresponding to the weight reduction hole 20 on the ECU bracket 21. The positioning block 7 is embedded in the weight reduction hole 20. When the conveyor belt 5 transports the ECU bracket 21 to the detection point, the mounting plate 1 rises, and the sensor 2 on the mounting plate 1 contacts the corresponding nut on the ECU bracket 21 for detection. The mounting plate 1 is provided with a top pin 8, the diameter of which is adapted to the diameter of the mounting hole 4 of the unwelded nut 3.
[0020] In the above specific technical solution, the ECU bracket 21 is placed on the conveyor belt 5 to achieve continuous detection of the ECU bracket 21. The ECU bracket 21 is positioned by the positioning block 7. When the ECU bracket 21 is conveyed to the detection point, the mounting plate 1 rises. The sensor 2 on the mounting plate 1 detects the welded nut 3. If the sensor 2 detects that the nut is missing from the weld, the sensor 2 sends a signal. At the same time, the top pin 8 will also rise. The installation position of the top pin 8 corresponds to the position of the mounting hole 4 of the unwelded nut 3. If the nut is incorrectly welded to the mounting hole 4, the top pin 8 will rise and lift the ECU bracket 21, so that the sensor 2 cannot detect the nut and the sensor 2 sends a signal. If the sensor 2 on the mounting plate 1 detects that the nut is welded correctly, the sensor 2 sends a signal.
[0021] The mounting plate 1 is connected to the output end of the lifting cylinder 9, which is mounted on the conveyor frame. The mounting plate 1 is slidably connected to the conveyor frame via the guide rod 10. The lifting cylinder 9 is used to lift the mounting plate 1, thereby enabling the sensor 2 to detect the welding nut 3.
[0022] The conveyor frame is equipped with a gantry frame 11 at the material feeding point. The slide 12 on the gantry frame 11 moves horizontally by a motor-driven lead screw mechanism. The slide 12 is equipped with a telescopic cylinder 13, and the output end of the telescopic cylinder 13 is equipped with a vacuum suction cup 14.
[0023] One side of the conveyor is provided with a collection box 15 for collecting ECU brackets 21 for collecting incompletely welded and mis-welded nuts.
[0024] In the above specific technical solution, if the sensor 2 transmits a signal of miswelding or missing welding of the nut, the telescopic cylinder 13 drives the vacuum suction cup 14 to descend, and the vacuum suction cup 14 adsorbs the ECU bracket 21. Then the vacuum suction cup 14 rises, and the slide 12 moves horizontally through the lead screw and guide rod mechanism. When it moves above the collection box 15, the vacuum suction cup 14 releases the ECU bracket 21, and the ECU bracket 21 falls into the collection box 15.
[0025] The conveyor belt 5 is provided with a collection box 16 below the end of the conveyor belt. The collection box 16 is used to collect qualified products. A rotating cam 17 is provided above the collection box 16. The two rotating cams 17 are located at both ends above the ECU bracket 21 and are connected by a connecting rod 18. The connecting rod 18 is connected to the output end of the drive motor 19. When the ECU bracket 21 is conveyed to the lower layer of the conveyor belt 5, the rotating cam 17 rotates and its distal end contacts the ECU bracket 21, which can push the ECU bracket 21 away from the positioning block 7.
[0026] In the above specific technical solution, when the sensor 2 transmits a signal that the nut welding is correct, the ECU bracket 21 is conveyed to the upper part of the collection box 16 on the lower layer of the conveyor belt 5, the drive motor 19 is started, and the drive rod is driven to rotate. The rotating cam 17 rotates, and its distal end contacts the ECU bracket 21, which can push the ECU bracket 21 away from the positioning block 7, so that the qualified product falls into the collection box 16.
[0027] The above embodiments are merely exemplary embodiments of the present utility model and are not intended to limit the present utility model. The scope of protection of the present utility model is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present utility model within its substance and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present utility model.
